老师：Hello everyone, welcome to my class. Today we'll talk about the useful structures in Unit 5. Before we get started, let's first take a look at learning objectives. In this class, you will analyze the difference in meaning and use of the ing form. You also summarize the different structures of the ing form. After that, you will rewrite sentences and complete passages using the ing form. And finally, you will talk about helping elderly people and avoiding accidents in life using the ing form.
老师：Now let's get started. Here we have a few sentences from the reading passage. Please think about what is a function of the ing form in each sentence below. And also, can you express the same ideas without using the ing form.
